1.2÷8=3÷(5x+7) nmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm

Answer 1

Answer: $x=2.6$

Step-by-step explanation:

Given the following equation:

$\frac{1.2}{8}=\frac{3}{5x+7}$

You need to solve for  the variable "x" in order to find its value.

To do this, you can follow the steps below:

1. Youst must multiply both sides of the equation by $5x+7$:

$(5x+7)(\frac{1.2}{8})=(\frac{3}{5x+7})(5x+7)\\\\\frac{6x+8.4}{8}=3$

2. Now you have to multiply both sides of the equation by 8:

$(8)(\frac{6x+8.4}{8})=(3)(8)\\\\6x+8.4=24$

3. The next step is to subtract 8.4 from both sides of the equation:

$6x+8.4-(8.4)=24-(8.4)\\\\6x=15.6$

4. And finally, divide both sides of the equation by 6:

$\frac{6x}{6}=\frac{15.6}{6}\\\\x=2.6$
